Rome - Caelius hill area

The south eastern side of Rome from the Palatine and Forum to the city walls.

During the archaic period of Rome the hill used to be called "Mons
Querculanus" due to the numerous oak trees growing on it. The 6th
king of Rome, an Etruscan called Mcstarna but referred to by the Romans as
Servius Tullius, renamed this hill Caelius. He did so in honour of his ally
Caelius Vibenna: another Etruscan who had given his life to assist Servius in
escaping imprisonment and breaking the power of the Etruscan priesthood and
nobility.

The major site is the church of San Giovanni in Laterano. This was the Papal
residence before the move to Saint Peter's and the Vatican and had been donated
to the church by Emperor Constantine.
